The £1m project will create development sites, enable the expansion of car parking, and cater for future town centre redevelopment.

The new road is being built partially along the existing Henry Street route.

Rhondda Cynon Taf Council say "environmental enhancements" to the main shopping area - Oxford Street - will follow once the road is completed.

Coun Eudine Hanagan, cabinet member for better public services and transport, said: "We are delighted to see work is under way on this vital new road as part of our wider plans to regenerate the area."

Alun Griffiths (Contractors) Ltd are undertaking the work, which is funded by the Welsh Assembly. The road is due to open in December.
